碘缺乏病的监测结果动态分析

Dynamic Analysis of Iodine Deficiency Disorders

目的了解那坡县食盐中碘元素的含量情况以及尿碘检测碘含量情况,为消除碘缺乏病提供科学依据。方法根据《实现消除碘缺乏病目标县级考核评估方案》中所制定的评定标准,和按照卫生部2007年颁布的《全国碘缺乏病监测方案(试行)》。碘盐检测采用GB/T 13025.71999中直接滴定法,川盐、强化盐采用氧化还原滴定法测定,尿碘检测采用WS/T 107-2006催化还原分光光度法,合格碘盐判定标准为20～50mg/kg,合格尿碘判定标准为>100μg/L。结果 2010年前三年中碘盐合格率、合格碘盐食用率和碘盐覆盖率2007年为97.19%、96.18%、98.96%,2008、2009年均为100.00%,尿碘含量低于100μg/L的比例不超过20%。结论 2010年经省级考核评估,那坡县碘盐"三率"和尿碘含量均达到了国家碘缺乏病消除目标。

Objective To Napo County iodine in salt content and the detection of urinary iodine content of iodine, to provide a scientific basis for the elimination of iodine deficiency disorders. Methods According to ＂achieve the elimination of iodine deficiency disorders goals at the county level for examination and evaluation program developed by evaluation standards, and in accordance with the National Iodine Deficiency Disorders, the Ministry of Health issued in 2007, the monitoring program （Trial）＂. Iodized salt was detected by direct titration of GB/T 13025.71999, Sichuan salt, to strengthen the salt using redox titration, the detection of urinary iodine using WS/T 107-2006 catalytic reduction of spectrophotometric criteria of qualified iodized salt is 20-50mg/kg, qualified urinary iodine criteria of 7 100μg/L. Results Three years before 2010, iodized salt pass rate of qualified iodized salt and iodized salt coverage in 2007 to 97.19%, 96.18%, 98.96%, 2008, an annual average of 100.00%, urinary iodine content of less than 100μg / L ratio does not exceed 20%. Conclusion In 2010 by the provincial examination and evaluation, Napo iodized salt ＂three rate＂, and urinary iodine content up to the national iodine deficiency disorders elimination target.
